Grinding a dead board down to bare chip level is one of those jobs where a shaky hand or the wrong tool ruins a board you could have saved, and that's exactly the gap the AiXun 2nd Gen Chip Grinding Machine fills on a technician's bench. Instead of relying on a hot air gun and a scraper to remove touch ICs, CPUs, or NAND flash chips, you get a dedicated CNC-style grinding platform built specifically for smartphone motherboard work. The machine is powered by a customized aviation high-power inner rotor brushless motor, which AiXun tuned to hit a 24000r/min maximum no-load speed while still keeping enough torque to cut through chip molding and epoxy without bogging down mid-grind. That matters on a busy repair bench, where you're not grinding one board a day, you're grinding several, and a motor that loses power under load slows your whole workflow down. The CNC ER8 collet holds the emery grinding heads securely, and the machine ships with two head sizes, 2.5mm and 4.0mm, so you can switch between fine detail work around small touch ICs and broader passes on larger CPU packages without needing a second tool. Precision on this machine comes from three separate adjustment points rather than one guess-and-check dial. The vertical micrometer sets grinding depth, so you control exactly how far the head cuts into the chip surface, which is the difference between a clean grind and a gouged pad. The horizontal micrometer sets grinding width, letting you widen or narrow your pass across the chip. A stop block fixes the grinding movement length, so repeated passes stay consistent instead of drifting further with every stroke. Combined with the linear guide rail and bilateral limit block design, the whole setup is built so your positioning point stays exactly where you left it, which is critical when you're working millimeters away from a live PCB trace. The universal fixture that comes standard rotates at multiple angles, which solves a real problem technicians run into constantly: no two motherboards are shaped the same, and a fixed clamp that only holds boards straight-on is useless the moment you're working on an oddly shaped or multi-layer board. Being able to rotate the fixture block means you position the chip under the grinding head correctly instead of forcing the board into an awkward angle and risking a slip. On top of the mechanical build, the 0.8 inch OLED display gives you a live readout of rotate speed status, so you're not grinding blind or guessing whether the motor is running at the speed you set. You adjust speed on the fly depending on the material you're working through, slower for delicate touch IC work near sensitive traces, faster for stripping heavier CPU molding, and the screen confirms the change in real time. A POST buzzer prompt on startup adds a basic self-check layer before you begin work, and LED lighting built into the unit means you're not grinding in shadow when you're trying to see a chip edge clearly. AiXun also built in remote online software upgrade support, so the machine's control firmware can be updated without sending the unit back or opening the housing, keeping it current as AiXun refines the platform. For technicians in Pakistan running a repair shop or service center, this kind of tool earns its place on the bench during chip-level rework: removing a touch IC that's causing a display problem, grinding down a CPU package before reballing after a hardware fault, or clearing NAND flash chips off a board with a dead-after-flash issue where the original chip needs replacing rather than reflashing. It's not a tool for basic software marna jobs like FRP lock or pattern unlock work, it belongs at the hardware rework stage, after diagnostics confirm you're dealing with a chip that needs physical removal rather than a flash or software fix. The compact footprint, close to an A4 sheet of paper in size, means it sits on a crowded workbench without eating up the space a full CNC rework station would need, while still delivering CNC-level positioning accuracy for the specific job of chip grinding. If your shop handles motherboard-level repair, board swaps, or reballing services regularly, this machine replaces the inconsistent manual grinding methods that risk damaging adjacent components, and gives every technician on your team a repeatable, controlled process for chip removal instead of one person's steady hands being the deciding factor in whether a board survives the repair.
